you shouldn't have much to worry about as long as you don't go "high-speed" wheeling. Also, you shouldn't leave your hubs locked just to have shift on the fly because that means the cv's are spinning with the wheel in 2wd, basically making it like on of our 4runners. you probably knew that though, but that's how I interpretted your above post.

 

yeah i know its not a good idea even at stock height.... so now i really shouldnt lock them.

 

Hey Rowan how do your saw's ride with that much lift? I dont think I need 4 inches though, more like 3-1/4 to 3-1/2 like I have from my OME's. They ride real stiff and provide about 0 inches of flex. I would want the saw's to be a significant improvement if I was to look into them cause my money doesn't grow on trees. Any incite would be greatly appreciated. Derek

 

they ride okay. more stiff than when i only had 2" lift on them. but they are fine. as for flex... i havn't really tested it, but i would imagine it is not great. never was good though. i doubt there is a lot of downward travel either. i took my swaybar off though... so maybe my flex wont be too bad now.
